Improved metallic coffin



GEORGE NEARSTHEIMER, OF O1NCINNATI, OHIO.

Letters Patent No.V 88,728, dated April 6, 1869.

IMPROVED lwETALLIC COFFIN.

*-j-*QFO-v- The Schedule referred to in these Letters Patent and making part of the Same.

To 'whom it may con cern Beit known that I, GEORGE NEARSTHEIMER, of Gincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Metallic Oofns; and I hereby declare the following to be a full, clear, andv exact description thereof, reference being had to the accompanying drawings, making part of this-specication. p

My invention relates to the construction of metallic cofns, having cast-zinc supports at the angles and at other places within the-rims, which cast-zinc supports also present s ucient substance to -receive the screws or bolts necessary to fasten the top and bottom togetber.

It also relates to a form of safety-valve capable of 4being adjusted to sustain a designated '.pressure, but

to open and relieve the interior of the coffin of such pressure as would endanger the bursting 'of the coflin.

Figure 1 is a longitudinal section on the line X-X, g. 2. 4

Figure 2 is a horizontal section on the line Y-Y, fig. 1.

Figure 3. is a transverse section on the line Z-Z, fig. l. p v

The bottom of the co'in-body is formed of a piece of galvanized sheet-iron, A, -stiifened by ribs a of similar material; g

The sides B are formed of pieces of sheet-zinc, whose upper edges are bent over and inward, as shown in iigs. 1 and 2, so as to form a stiif,'as well as ornamental hollow rim, C.

This rim G receives at each angle an angular plug,

D, of' cast-zinc, having 'a screw-threaded perforation, surrounded by a boss, E, which rises through a corresponding hole in the rim, and enables the two to be soldered together.

F is a number of smaller plugs, similarlysecured within the rini, and like the plugs D, provided with screw-holes. I

These screwholes in the said plugs serve as nuts to receive the'screws G, employed to fasten down the lid H of the eoflin. The said plugs also assist to stay and stiifen the rim.

H' is a galvanized-iron frame, soldered underneath the rim ,of the lid.

C is a galvanized-iron frame, similar in construction to H', and forming the bottom of the hollow ri'm O.

I are ribs, of galvanized sheet-iron, whose 'pper and lower ends are respectively soldered to the rim and the bottom.

These ribs have soldered to them cast-zinc nuts J for the ha nelle-screws. The-se ribs serve a double purpose, namely, that of stiening the coin-body, and that of affording secure points of attachment for the handles.

The coffin-lid has a conical perforation, M, to aiford a seat for a corresponding poppet-valve,N, whose screw-threaded stem, O, passing downward, and being furnished with a suitable nut, 1:', and with Va spiral spring, Q, the valve is held down upon its seat with a greater or less pressure, according to the tension of the spring, and this tension is capable of being graduated even after the closure ofthe coin, by simply screwing the stem O-to the right'or left.

The -rotation of the nut is prevented by a tongue, R, occupying a slot, s, in the chamber S, which depends from the under side of' the lid..

This tongue may extend entirely through the slot s, as shown in figs. 1 and 3, and may, in connection with a scale, T, marked on the chamber, indicate the pounds pressure to which the valve is or may be set.

I claim herein as new, and of my invention- 1. The arrangement of-the bottom, A a, sides B, hollow rim G, angular and screw-threaded plugs D E, and frame O', for the purpose set forth. -V

2. In combination with the elements A a, B, C, D E, and O', the short plugs F. p v

3. The described combination of the parts A a, B, C, D E, F, and O', with the ribs I and nuts J, formed 'and secured as set forth. p

4. The screw-threaded stem O, the nut P, spiral spring Q, the tongue R, slot s, in the chamber S, and thegraduated scale T, constructed and arranged to act as and for the purposes set forth.

In testimony of which invention, I hereunto set my hand.

GEORGE NEARSTHEIMER.
